MoveMaterialAttachmentToGround()

void MoveMaterialAttachmentToGround ( notnull EntityAI parent, Man player, notnull ItemBase attachment, notnull InventoryLocation invloc, string partName )

protected

The method does not care about the amount of materials that should be returned based on the cached quantity in the ConstructionMaterialData struct. If we start using this method for e.g. drop of materials that are not attached and locked to the construction parent then we need to change the method to handle the quantity accordingly
